According to Wikipedia:
Lunarpunk is a subgenre of solarpunk with a darker aesthetic. It leans toward fantasy and its themes include night settings – often featuring bioluminescence and purple colors, spirituality or the occult, green cities, sustainable technologies, and a more introspective side of solarpunk utopias.
This space also celebrates the feminine energy of the moon with its cyclical pull on the emotions and tides. The shadows of life, just like the luminance of nature, appear in waves that return again and again. Be patient as they flow through you and within each other.
